Nitroso compounds have emerged as highly valuable reaction partners or reagents in organic synthesis due to their rich *** versatile profile of these compounds allows them to function as electrophiles, nucleophiles, diradicals, and radical acceptors in diverse transformations. In recent years, notable progress has been made in harnessing photochemical reactions with nitroso compounds to prepare N,O-containing structures using mild and eco-friendly conditions. Various nitroso compounds like nitrosoarenes, acyloxy nitroso compounds, N-nitrosoamines and nitrites have received significant attention for their ability to introduce NO moieties into complex molecules that are otherwise difficult to access. In this review, we provide an overview of the recent advancements in the visible light-induced conversion of nitroso compounds, with particular emphasis on their role as bifunctional reagents and acceptors of radicals, carbenes and nitrenes.

《全唐文》在借鉴金石学传统基础上确立了只录拓本见在者的基本原则。由于尽力搜求拓本,且所用拓本大多质量较好,所以虽未能尽数收录已出土墓志、充分利用已有成果,最终迻录数量却居各家之上,整体录文质量也较高。这表明学界对《全唐文》的质疑,以及其不征及时人研究成果的批评有失公允。至于《全唐文》编者为保存出土墓志文献价值,放弃原本可以做到的唐文之全的行为,也彰显出其以学术价值为先的立场,值得后人肯定。

系统收集有关数据,揭示CPI与国内旅游需求的相关关系,结果发现:①CPI与国内游客、旅游花费、人均旅游花费的环比增长率呈反相关关系,与城镇及农村国内客流量、人均花费及总花费均呈反比关系;②与城镇相比,CPI对农村客流量的影响相对较小,对农村游客人均花费的影响相对较大;③在CPI上升时,农村居民可能减少每次出游的花费从而保证旅游次数,城镇居民则可能减少出游次数从而保证旅游质量;④CPI对人均旅游花费的影响大于人均可支配收入,人均可支配收入对客流量和旅游总花费的影响大于CPI,在CPI与可支配收入增长速度相同的情况下,客流量和旅游总花费仍将保持持续增长。

BACKGROUND: Portal hypertension is a common diseasewith a high mortality and serious effect on the life quality ofpatients. Presently, shunt and disconnection are commonlyused for surgical treatment of portal hypertension. The aimof this study was conducted to analyze the results of a modi-fied Sugiura procedure for the management of 160 cirrhoticpatients with portal ***: The results of a modified Sugiura procedurefor the treatment of 160 cirrhotic patients with portal hyper-tension from January 1991 to July 2002 were ***: The operative mortality for the procedure waszero. Postoperative intra-abdominal bleeding was noted in2 patients, drowned lung in 1, pneumonia in 1, and splenicvenous thrombosis in 4. Of the 160 patients, 157 (98%)were followed up from 6 months to 11.5 years. Of the 157patients, only one died of hepatic coma 6 years after opera-tion, and 3 of rebleeding. The absolute and relative survivalrates were 97.5% (156/160) and 99% (159/160), respective-ly. The absolute and relative occurrence rates of hepatic co-ma were 2.5% (4/160) and 0.6% (1/157), respectively. Theabsolute and relative occurrence rates of rebleeding were3.8% (6/160) and 1.9% (3/157) , respectively. In 96 of 116Child B patients (82.8%), liver function improved frompreoperative class B to A 3 months after operation. Sixty-five patients were subjected to gastroscopy and 22 patients,esophageal barium photography 6 months after ***-esophageal varices disappeared in 56 patients(64.4%, 56/87), obviously improved in 30 (34.5%, 30/87),and unchanged in 1 (1.2%, 1/87). The occurrence rate ofportal hypertensive gastropathy (PHG) was 13.9% (9/65).CONCLUSION: Our results showed that the modifiedSugiura procedure is effective in the treatment of portal hy-pertension, with a low rate of operative complication,bleeding recurrence, and hepatic coma.

Objective： To observe the effects of apigenin on cell proliferation of human pancreatic carcinoma cell line BxPC-3 in vitro. Methods：The inhibitive effects of apigenin at different concentrations （0 μmol/L, 100 μmol/L, 200 μmoL/L, and 400 μmol/L） on human pancreatic carcinoma cell line BxPC-3 were detected by MTT assays, transmission electron microscope, agarose gel electrophoresis and flow cytometry. The immunohistochemistry was used to detect the expression of Bcl-2 and Bax gene. Results： Apigenin at different concentrations could inhibit the proliferation of human pancreatic carcinoma cell lines BxPC-3, and the inhibitive effect was dose-dependent. The cell cycle of pancreatic carcinoma cells was arrested at G2/M phase. The results of immunohistochemistry showed that the density of apigenin increased, and the expression of Bcl-2 gene was reduced gradually, At the same time the expression of Bax gene was enhanced. Conclusion ：Apigenin could inhibit the proliferation of human pancreatic carcinoma cell lines BxPC-3 in vitro. The effect of apoptosis was accompanied with the expression of Bcl-2 decrease and Bax increase.
